Control method for reducing yarn breakage of spinning machine

Abstract

The invention discloses a control method for reducing yarn breakage of a spinning machine. When a fan starts, a ring rail moves to the spinning starting line and continuously moves upwards; when the ring rail moves to the spinning line, a main motor starts running at a low speed, and the ring rail moves downwards from the spinning line to the starting spinning line, and then spins at the low speed. When the running time is equal to Pd, a position sensor sends signal for spinning in the middle. The ring rail moves upwards to the spinning line and then moves downwards to the starting spinning line, and then balloons are opened timely, so that the balloon wavelength is shortened, the yarn tension is reduced, and the spinning yarn breakage is dramatically reduced. The running time of the ring rail motor can also be set to 5 seconds from the beginning of the fan start, and if the starting spinning position sensor is out of order, the ring rail motor moves upwards and stops in five seconds.

Description

[0001] The present invention is a divisional application with the application number 2013100334239, the application date is January 29, 2013, and the title of the invention is "a control method and device for reducing yarn breakage of spinning frame". technical field [0002] The invention relates to a control method for the spinning process of a spinning frame, which is suitable for the spinning frame, in particular to a control method for reducing yarn breakage of the spinning frame, and belongs to the technical field of textiles. Background technique [0003] In the textile industry, the spinning frame is usually used to spin on the bobbin 1, and reducing the breakage rate of the spinning frame during spinning is the goal that the industry has been pursuing. Traditional equipment still in use in the market, such as FA502, FA503 and A513, etc., mainly use AC contactors to control the spinning process of the entire spinning frame. control. In order to reduce the yarn break...

Problems solved by technology

Traditional equipment still in use in the market, such as FA502, FA503 and A513, etc., mainly use AC contactors to control the spinning process of the entire spinning frame. control

In order to reduce the yarn breakage rate of the spinning frame, at present, frequency converters are generally used to control the realization. However, due to the large number of old spinning frames mentioned above in the textile industry, these spinning frames are transformed. The frequency converter of each device is combined with the The cost of PLC is nearly 10,000 yuan. It is very difficult for many textile enterprises using old equipment to realize this method of control, which affects the product quality and output of these enterprises.

On the other hand, flying flowers are easy to block the heat dissipation system of the frequency converter, which is the disadvantage of the old type of spinning frame controlled by the frequency converter, and it is also the main reason that the frequency converter is easy to burn out or even cause a fire after being used for a long time
